Can I use the T1, T4s or T8s with the F1 system?

Yes. The F1 system is compatible with the ToneMatch audio engine.

You’ll need a stand-alone power supply for the T1 or T4s, but the T8s comes with a power unit.

There is no ToneMatch port on the F1 812 or sub, you’ll need to use 6.3mm TRS cables from the master out.
